\ To all whom ct may concern. v

Be it kncwnl that I, CHARLES SPIELMAN, a citizen of the United States,residing at Queens Borough, New York city,v in the county of Queens andState of New York,

have invented certain new and useful Im- Y machines, andit is my objectto simplify and cheapen the construction of such stamps so thatthey maybe more quickly and easily assembled and alined, to. provide a simpl1-fied form of stop catch` to -hold the printing head down in the mainframe while inking the pad `or setting the type wheels, lto providetheprinting head with unitary, combined ratchet pawls and springs whlch maybe independently adjusted to aline the symbols on `the type wheels, and'finally to :provide the ink pad carrier links with eX- tensions toincrease their bearing surfaces on the main. and` sub-'frames to.prevent cramping vvand twisting althoughl they `are loosely mounted ontheir pivots instead of being riveted or screwed `in position.

In the drawing Fig. 1 is a sectional view of my `improved hand stamp; adater being selected for purposes of illustration; Fig. 2 a rear viewvof the lower part of the structure of Fig. :1; Fig. 3 a front view ofthe lower :part of the structure 4of Fig, 1; Fig. 4 a side viewof thelower'part of the structure of Fig. 1,`partly inisection; Fig. 5 asectional view ot' the lower ypart of the structure :of Fig. 1,*on theline 55 thereof; and Fig. 6 a detail view of the combined spring .andpawl. i

The stamp consists of the usual main frame composed of sides 1 and 2connected by 4a 4top plate 3, -in which mainvfr'amelthe printing head.composed of a sub-frame `5 carrying printing wheels 6 is mounted. Thisprinting `head is reciprocated inl the main frame by a stem 7 secured tothe sub# frameV 5 andpassing through the .top `3 of the main lframe. `Tonormally hold the printing head up a spring 8 lis coiled around the stem.7 and bears against the flanged bottom of a sleeve 9 surrounding it latone end, the other endgof the `spring bearing against an abutment washer10 secured to the upper part of the stem. 'A knob 11 on the upper 4.endof `the stem affords a hand Grip. c To lock the printing wheel .head inthe downward position while inking the pad or setting the Wheels awasher' 12 rovided` with a domed top anda lip or hool 13 is placedbetween the lower end of the sleeve `Qiand the topof the main frame withthe hook engaging the edge of the top late. `This .forming ofthewashergives a nished base effect to the sleeve 9. The stem 7 is groovedat 111 so that when the stem is pushed down the washer 12, through which.it passes, may

4be pushed intothe notch to lock the printing head in downward position.This washer 12 is held in position by the pressure of the spring on thesleeve which holds the washer slidably between the end of the sleeve andthe top `ot the main frameNfA projection 26 on the inside of the washerengages a groovev27 -in the top of the `rnain .frame and prevents `anytwisting movement of the washer. In this way the ylock is held in placewithout the use of any yspecial securing means `and the bolts andpivoted washers or levers heretofore used `for this purpose areeliminated. p

Heretofore it has generally been customary to hold thepr'inting wheelsin alinement by pawls pivoted toy the sub-frame ,and engaging ratchetwheels secured to the Ktype wheels, lthe pawls being forced intoengagement by. .a plurality of springs struck up from a single piece ofmetal andbearing against the pawls. I employ` a .separate spring 14 foreach printing wheel and secure the pawl I15 directly on it. The upper'part ofeach spring has an elongated screw hole 16 and is secured to thesub-trame 5 by a screw 17, as shown in Fig. 3. Each pawl 15 engages ayratchet wheel 18 secured toa type wheel. To aline lthe printingysy1nbols on the type wheels in proper ,printing lposition the springsare slid upor down on the sub-frame to turn thewheels on their axes,while a pawl `engages a ratchet wheel, untilthe symbols on the wheelsare exactly alined in printing positiomafter which the screws .are`driven home. In this `way slight variations in the type wheels and`their attached ratchet wheels may be compensated for. i. i l i.

To further afford quick and easy assembly of the machine the ink padcarrier 19 is pivoted to the main frame on a pin 20, one endrof whichscrews into one sideof the main frame; The ears of the ink pad carrierhave a pin 21 passing through them which pin is long enough to extendbetween the inner walls of thesides of the main frame. Each side of thesub-frame 5 has a studv 22 thereon and a pair of links i22%--A 24 arepivoted on the ends of the pin 21 and on the studs 22 so that as theprinting head reciprocates the ink pad carrier will swing out. on thedown stroke and against the type wheels on the up stroke. Y

. The loose pin 2l is always inside the boundaries of the main frame sothat no mechanical fastening is required to hold vit in pov sition. Thelinks lie in the spaces between the main frame and the sub-framecarrying the printing wheels and are held on their pivots withoutriveting or screws. rl`he linksextend outwardly at the top and in'-wardly at the bottom as best shown in Figs.

l and 4, to afford increased bearing surfaces. against the outer face ofthe sub-frame and the inner face of the main frame to prevent crampingor twisting which `might A otherwise occur due to the fact that thelinks are not screwed or riveted in position. The notches inthe-opposite edges of the links are necessary to clear the pin 20 and lthe axis on whichv the type wheels revolve.v

. Openings 25 may be made in the bottom edges of the sides of the mainframeto indicate the printing point. I

I claim:- I l.. A numbering machine comprising a main frame having sidesand a top, a cirthe stemand'within the sleeve with one end bearing onthe sleeve and -an abutment on the upper portion of the stem againstwhich the other end of the spring presses whereby the washer is held inslidable position to engage the stem groove to lock the printing head indownward position.

f 2.4i- Vnumbering machine comprising a main frame having sides and atop, `a grooved stem passing through said top, a

" printing head secured to one end of l the stem and 'adapted toreciprocate between the side walls of the frame, a washer on the stembearing ldirectly against the outside ofthe frame top and adaptedtoengage the stem groove, a hooked lip on said washer extending over theedge' of the frame top to position the same, a sleeve surrounding thelower .part of the `stem and,v bearing on the washer, a springsurrounding the stem and within the sleeve and an abutment on the` upperportion .of the stem against which the other end of the Aspring,pressesYwhereby the washer is slidably held in position to engage the stemgroove to lock the printing head in downward position.

. 3. A- numbering: machine comprising a main frame, a stem therein, aprinting head on said stem adaptedto reciprocate within the frame, saidprinting-head comprising a plurality lof typeiwheels vand attachedratchet wheels, flat springs secured at one end to said printing head,a` pawl rigidly secured to thefother end of leach of said springs in`position -to engage a ratchet wheel, said lsprings being provided withelongated slots through which the securing means extend -wherebythe'pawls'may be positioned to hold the type wheels in aline'- ment Y, u

l 4. A -numbering machine comprising a main frame,astem therein, aprinting head on the `stem adapted to reciprocate in the y ends of the'links are loosely pivotedand studs on the printing head to which theother ends of the` links are loosely pivoted, the link-extensionsaffording increased bearing surface and preventing cramping and binding.

`v5. A numbering machine comprising a main frame having sides and agrooved top, a' circumferentially grooved stem passing through said top,a printing'head secured to )neend ofthe stem andadapted to recipro- :atebetween the side walls of the `main rframe," a washer, a projectionthereon',I said washer yencircling the ystem with the projection in thegroove in the frame top and bearing on the latter, lsaid washer beingadapted to kengage the stem'groove, a sleeve surrounding the lower partof the stem, a springen the stem within the sleeve .with one end bearingthereon, and an abutment on the upper part of the stemag'ainst which theother. end ofthe springpresses, whereby the. washer is in -slidablelposition to engage the stemgroove to lock the printing head .indownwardposition.` e
